The Debating Society is the oldest society at the school and was started in 1896. They meet once a week (Tuesdays 17:30 - 19:00) for internal debating evenings as well as for fun evenings. They take part in the district debating league against other local schools. At present there is a senior team and a junior team, but they hope to increase participation to include two teams at each level. Sides take part in Derby Day encounters and travel away to various sporting destinations, as well as hosting debates during home fixtures. The Society is extremely popular and is open to all Grey boys.
